T0 @ZZ whom t may concern.-

Be it known that I, CHARLES P. HowE,a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Farm-Gates, of which thefoi lowing is a specification, reference heilig had therein to theaccompanying drawings.

My invention relates to certain novel and valuable improvementsin thatclass of swinging gates which are adapted to be opened and closed bypersons approaching them in vehicles without necessitating the stoppingand alighting ofthe occupants; andthe invention consists in the improvedfeatures of construction and combination of parts, which will be fullyunderstood from the following description and claims, taken inconnection with the annexed drawings, in which- Figure lis a perspectiveview of a gate pro' vided with my improved operating devices; Fig. 2, adetail plan view of a portion of the gate, showing the hingc-post inhorizontal section; and Figs. 3 and 4, detail side elevations of thehingepost, taken from different sides of the same.

Referring to the annexed drawings by letter, A A designate the twogate-posts, which are arranged on opposite sides of the roadway, and1li-designates a post on one side of the roadway, to which the gate islatched when fully opened, to allow a vehicle to pass.

The gate B may be constructed of wood or metal, like any ordinary farmgate, and itis attached to the post A by long hinges C C, each composedof eyebolts a a, secured to the vertical gate-post A, and an eyebolt,a', secured to the vertical bar D of the gate,through the eye of whichbolt passes a headed bolt or pintle, I, secured to the eyes of the boltsa a, as shown in Fig. 4 of the annexed drawings. It will thus beobserved that the gate B can be raised or lowered vertically, and alsoswung around one quarter of a circle from post A to post A2. To thevertical bar D', at the free end of the gate, I apply a latch, c, whichis adapted to engage either with a beveled catch, c', on post A', orwith a similar catch, c?, on post A. To the upper end of the gate-bar D,I rmly bolt two rigid strap-irons, E E, which` rise verti cally andafford bearings for the short shafts (No model.)

of two rollers, F F', arranged at asuitabledistance apart between saidstrap irons, and pref erably slightly tapered Vhen the gate is shut, asindicated in full lines, Fig. 2, the upper roller, F, rests upon thelowest part of one limb, g, of a segmental cam shaped rail, G, which isrigidly secured to the post A above the upper hinge C, and when the gateis fully opened the said roller F rests upon the lowest part of the limbg of said rail G.

The rail G is bent through somewhat more than onehalf of a circle; andit consists of two inclined planes or limbs, g g', terminated by angularportions g2 (fl, through which the screws or bolts pass that rigidlysecure lthe rail to the post A, as shown in Fig. 2 of the aunexeddrawings.

At g'n is a rounded ridge, which is the highest point ofthe saidinclined planes, and at g is astraighthorizontal portion of the railwhich is at right angles to the post A and designed to render the railcompact and at the same time afford the proper length of track.

A'l designates a horizontal arm or bracket, which is rigidly secured tothe post A parallel with the roadway, and to which is fulcrumed a longlever, I, the shortestv arm of which is connected by a rod, N, to aneyebolt or staple, L, secured to the vertical hinged gate-bar D justbelow the upper hinge C. The shortest arm of the lever I is alsoconnected by a link, i, to the shortest arm of a lever, K, which isfnlcrumed on the post A2 at a suitable height vfrom the ground. From thelongest arms ot the levers I and K depend wires having rings or othersuitable handles attached to them,by which a person riding or on footcan operate said levers and open or sh ut the gate.

It will be observed that the vertical irons E E receive between them thecam'rail G; also that the distance between the two rollers F F is suchas will allow the gate to beraised bodily the proper height before thelower roller, F', impinges against the under side of the camrail G.

In operation, suppose the gate is shut, as indicated in Fig. 1 of theannexed drawings, and a person riding or walkin g in the roadwayapproaches it in either direction, he will pull on the longest arm ofthe lever nearest him,

which will lift the gate bodily until the lower roller, F', bearsagainst the bottom of the limb or inclined plane g of the rail G, when,continuing to pull'on said lever, the roller F' will ride up saidinclined plane, and thus swing the gate around until the ridge g3 isreached,when the gate is allowed to descend and the upper roller to bearupon and roll down the inclined plane g, thus completing the opening ofthe gate by swinging it around and causing its latch c to engage withthe catch c2 on the post A. After the person has passed through thegateway far enough to reach the wire depending from the opposite lever,he pulls on the long arm of this lever, and thus raises the gate freefrom its engagement with the post Aaud causes the lower roller, F', tobear against the bottom side ofthe inclined plane g of cam G. Bycontinuing to pull on said lever the gate will be swung around untilroller F reaches the ridge f/3 of said cam, at which point the gate isallowed to descend until the upper roller, F, bears upon the top oftheinclined plane g of the cani G, when the gate will swing shut by itsown gravity and be latched to the catch on post A.

A person walking will open the gate by simply unlatching it from itspost A and swinging it open on its hinges, when it will-swing shut againby its own gravity; or, in other words, by the upper roller, F,descending the inclined plane g ofthe cam-rail G.

It will thus be observed that in moving the gate by means ofthe leversfrom a latched position the first eighth of a circle thelower roller, F,is caused to act against the bottom of the cam-rail, after which thegate is lowered and the upper roller, F, allowed to descend on top ofthis rail. Vhen the gate is opened by a person on foot pressing againstit, only the upperroller, F, isbronghtinto action upon the top ofthecam-rail.

Having thus fully described my invention, I

what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a swinging gate adapted to be moved vertically,of a double inclined segmental cam-rail secured to a gatepost, androllers applied to upper extensions of the gate-bar above and below saidrail, substantially as described.

2. lThe combination, with a gate which is adapted to be swung`horizontally and to be bodily moved vertically, of elongated hinges, adouble inclined segmental track secured to the gate-post, the rollers FF/, adaptedto operate on opposite sides of this track, the levers I K,and a rod connecting the lever I to theV vertical hinged bar of thegate, substantially as described.

3. The combination of a swinging gate which is adapted to be movedvertically and which is connected to a gate-post, A, by elongated hingesG C, and provided with a latch, c, the posts A A2, provided with catchesand located with respect to the roadway as described, levers fulcrumedon said posts,linked together and connected to the gate by a rod, N, adouble inclined segmental cam-rail secured to said gate-post A, androllers jourualed in extensions of the gate-bar D and receiving betweenthem said cam-rail, substantially as described.

4. The combination, with the gate-postsA A and the gate hinged to theformer, so as to be movable vertically thereon, of the stationaryscgmental rail G, composed of the oppositely-inclined portions r/ g',united by a ridge, g, the said rail being attached to the hingepost A,and the rollers F F,journaled upon the inner post, D, ofthe gate andadapted to bear, respectively, above and below the said segmental rail Gin the operation of opening and closing the gate, substantially as setforth.

In testimony whereof I'afx my signature in presence of two witnesses.
